CARBONATOR.

)SPECIFICATION forming part Of LetterS Patent NO. 628,137, dated July 4, 1899. Application filed December 16,1898, {uerial No. 699,419. (No model.)

To all whom at 7nd concern:

Be'it known that I, DAVID BOYLE, a citizen of theUnited States, residing in Paterson, in the county of Passaic and State of New J ersey, have invented certain new and useful Improvements in Oarbonators; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such small particles, but while in this state isalso' considerably and thoroughly agitated, so that the mechanical combination between the liquid and the gas is'most completely effected.

The invention consists in the improved carbonating apparatus and in the combination and arrangement of its various parts, substantially as will be hereinafterpointed'out and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, Figure 1 is a View showing myimproved carbonating apparatus, partly in section. Fig. 2 is a top plan view-of said apparatus. Fig.

. 3 is a vertical sectional View of. a portion of the upper end of the apparatus, and Fig. 4 is a sectional View of the upper portion of an apei paratus constituting a slight modificationof my invention.

In said drawings, a designates a verticalcylinder having an integral flange ct at its lower edge, whereby through the medium of bolts or screws 1) itis secured to a base I). 0 indicates a cap which is screwed into and surmounts said cylinder.

c designates a vertical .revoluble shaft which is stepped at its lower end in the base I) and whichat its upper end penetrates the cap 0, being surrounded by a stuffing box d of ordinary construction upon said cap. This shaft is adapted to be rotated in any suitable manner-as, for instance, by means of a belt passing over apulley d, keyed upon, preferably, the upper end of said shaft. The

shaft c carries a series of paddles e, which may be formed into integral sets of substan*- tially propeller-like shape, each propeller or set of blades being preferably adjustably mounted'on said shaft by means of a setfscrewve'. Alternating with said propellers andlikewise preferablyadjustably mounted on said shaft are shallow perforated cups f, each cup being most desirably disposed in proximity to the propellerabove it. It should be remarked that both the propellers and the cups are nearly of the same diameter as the cylinder in the preferred form of my apparatus.

f designates a pipe communicating with the source of water-supply at one end, as hereinafter described, and projecting at its other end into the cylinder,extending through the cap thereof, in which it is screwed, and provided at its free end with arose or spray g.

g constitutes the conducting-pipe for the carbonic-acid gas. This pipe communicates with the cylinder 71., containing the supply, through a short tube h',in which is arranged apressure-gage 7;, and said pipe 9 communi-' cates with the cylinder (1 at points preferably between each propeller and its corresponding cup through other short tubes 1'. j designates a valve whereby the supply of gas to the pipe 9' and ultimately to thecylinder is controlled, said valve being arranged I which the coincident ends of said pipe andcoil project for this purpose) and controlled by a ball-float 70, also situated in saidcylinder. The coil j is directly connected with the source or supply of water. Said coil, furthermore, is inclosed within a jacket Z, forming,with the cylinder and its base, atank, within which and between said cylinder and the coil may be placed ice for refrigerating the water as it comes from the supply.

Z designates a gage communicating with the cylinder through the pipes m m, controlled, by the valves n 71, respectively, and adapted to indicate the height of the liquid that has been carbonated and collected in the bottom of the cylinder. 0 is a thermome ter projecting out of said gage, at the upper end thereof, and 0 is a small cock communieating with the lower end of said gage.

1) indicates one of the discharge-pipes of the apparatus. It is provided at its free end with one or more nozzles 1 controlled by valves q and to which the tubes connecting said apparatus with the bottles or other receptacles for the carbonated liquid may be applied. Several of these pipes 19 may be provided. Besides the one already described I have indicated at q where another one may be connected with the apparatus; but it is manifest that these pipes may have connection with the cylinder at any point below the normal surface of the charged liquid, as desired. It is only necessary here to remark that the liquid may be more or less completely charged at one level than at another for various reasons, and hence it maybe desirable to provide a number of the pipes 19, so that the operator may select the one whereby the liquid of the desired quality may be discharged.

In order that the air which collects in the top of the cylinder may be automatically allowed to escape, I have provided a valve 1', controlling the pipe r, that extends through the cap 0, said valve being carried by an angular lever s, fulcrnmed upon the top of said pipe and normally held downwardlythat is to say, with the valve closed-by means of a spring 8, connected to the cap. The lever s is operated and the valve opened by means of pins 15, carried upon one side of a wormwheel t',wbose teeth engage a worm u on the shaft 0, said wheel being journaled upon a standard a and projecting upwardly from and securedlto the cap 0. It should be remarked that the pins 15 are preferably removable from the wheel in which they are mounted. This provision is made in order that the number of pins which are acting upon the levers may be varied according to the number of bottlers operating the apparatus.

If necessary, a safety-valve e, controlled bya weighted levere, maybe arranged upon the cap 0, so that in case the pressure of the gas becomes abnormal it may escape whether or not the valve r is opened frequently enough to accomplish this end.

In the modification shown in Fig. 4 the vertical chamber 10, which corresponds to the cylinder (1, is preferablyrectangular in crossseetion. In' said modification the paddleblades or propellers w are revoluble in vertical planes, being mounted upon horizontal shafts cc, journaled in bearing-blocks as, dis posed in opposite wallsof the chamber 10, said shafts being rotated by means of a single vertical shaft 3 revolubly arranged outside of the chamber and carrying pinions y, engaging pinions 2 on the horizontal shafts. It should be remarked that the paddles of each set are in alternate arrangement with those above and below them. Instead of the eupsf perforated troughs z are mounted below each series of paddles w. The escape of the air is, in the case of this modification, permitted by means of a spring-actuated valve a arranged upon and controlling a pipe 19 screwed into the cap a of the chamber, said Valve being actuated by pins (Z carrried upon a disk 6 thatis keyed upon the shaft 1 For the purpose hereinbefore set forth the said pins may be removable. The mechanism on the lower end of this apparatus is substantially like that hereinbefore described and shown in Fig.1 with reference to the preferred form of the apparatus. The gas is supplied in substantially the same manner as hereinbefore described with reference to said preferred form of the apparatus; but the water is discharged from the supply-pipef through the medium of a perforated pipe f that extends across the chamber at its upper end.

It should be remarked that if desirable the pipe g may be provided with an extension 9 which will convey the gas into the cylinder at a point below the level of the liquid thathas collected after having been carbonated. Thus provision is made for a further carbonating of the liquid.

In operation, water being admitted from its supply and gas being admitted from the cylinder 71, the former will flow through the coil and the pipe f, being finally discharged from the rose g, whereby it is sprayed down- Wardly, and simultaneously the gas passes from its cylinder through the pipe g and the smaller pipes 'i and q into the main cylinder, wherein it immediately begins to rise. Meanwhile the shaft 0 and the propellers and perforated disks which it carries are being rotated at a high rate of speed, the consequence being that the water which is being .sprayed from the rose g is continually being further broken up into smaller particles by the blades or paddles and caused to thoroughly commingle with the rising gas, which is likewise and through the same me dium being broken up into myriads of particles. Owing to the rapid rotation of the propellers,there is a more or less tendency to drive back several times the water and the gas as, in its divided state, it meets said revolving propellers, so that the effect of the com mingling the water and the gas is not only produced by virtue of the fact that each is broken up into a great number of minute particles but also to the fact that their progress through the apparatus is greatly retarded.

The principal function of the perforated disks is to deliver the liquid to the subjacent rapidly-rotating blades or paddles in a finely divided or comminuted state, so that the bodies of liquid which engage said blades and which are by them violently agitated to effect the desired commingling of liquid and gas may be as small and as numerous as possible and directed against each entire blade. Furthermore, it is the function of the paddles to not only continue but to materially augment the breaking up of the liquid into small particles and the eifectuation of its commingling rated partitions or their equivalents for breaking up the liquid into small quantities or bodies as it passes through the apparatus and is subjected to the rising gas. I am also aware that it is old to employ blades or paddles to agitate the descending liquid; but I am not aware that it is old to employ these two elementsnamely, the blades or paddles and -the perforated disks or other partitionsin combination and of the character and in the disposition described for the purposes of securing the peculiar results above particularly referred to. i

As the carbonated Water collects at the bottom, it gradually rises if not immediately drawn off until the ball-float rises and shuts off the supply of Water. Meanwhile the air that is being formed is being intermittently permitted to escape by means of the automatic valve 1". As soon as the liquid which has been carbonated is sufficiently drawn off by the bottler or bottlers the float will again descend and permit more water to enter the apparatus. If no water appears in the gage Z, it will be obvious to the attendant that water is not being supplied.

It is to be noted that the disposition of the refrigerating apparatus relatively to the liquidsupply by virtue of the arrangement of the coil j in the refrigerating-chamber itself is such that not only is the liquid already carbonated and collected in thebottom of the cylinder kept cool, but the newly-carbonated liquid falling into it has practically the same temperature.

I have hereinbefore particularly referred to water as the liquid to be carbonated; but it is obvious that'the various beverages or liquids which are usually subjected to the carbonating treatment may be treated by means of my apparatus.
